A ground fault circuit interrupter (GFCI) for regulating the flow of current through a pair of conductive lines extending between a power source and a load. The GFCI includes first and second pairs of terminals located at opposite ends of the conductive lines, the first pair of terminals being designated for connection with the power source and the second pair of terminals being designated for connection with the load. A pair of electrical outlets are connected to conductive lines at a location between the first and second pairs of terminals. A circuit breaker is located in the conductive lines between the electrical outlets and the first pair of terminals. A ground fault detection circuit detects the presence of a ground fault condition in the conductive lines and, in response, generates a trip signal which is used to energize a solenoid that is ganged to the circuit breaker. A reverse wiring circuit is provided which generates an artificial ground fault condition when the power source is improperly connected to the second pair of terminals rather than the first pair of terminals. Once the power source is properly connected to the first pair of terminals, the reverse wiring circuit is instantly permanently disabled.
